Superimposed Lines look good, theres a bit of curving on the first page but its much better on the second.

Ghosted Lines subtle curve to many of them.

Ghosted Planes look good, much less curving on them.

Ellipse Tables have a few gaps in them but overall are very good.

Ellipses Planes ------------------------

Ellipses Funnels are good overall tho some are a bit crooked.

Plotted Perspective is good but you should avoid trying to correct lines that are off.

Rough Perspective there is a bit of wobble in your lines. I think you'll improve on this by doing boxes/other exercises

Rotated boxes don't look like they are rotating in the top left, definitely seeing improvement in the other corners especially in the bottom right.

Organic perspective starts out a bit rough but theres a lot of improvement over the pages.

You did well overall and are definitely improving quickly.
